Vodacom upgrade problems

I upgraded my wifi router beginning of March ( online). I recieved the device the next week, but the device was faulty. Its battery only lasts until midday then it dies. I requested a return after 4 days of recieving it (Well witin the 14 day policy). I sealed it in its box the day I called them and left it at my friends work for the pick up. The courier company only picked it up 2 weeks later.

I have called vodacom a million times since then. The router has still not been cleared from my account so I can redo my upgrade. And they still charged me for it. I will probably never get my money back and will continue talking to useless people that just do nothing about my problem. As soon as all my contracts expire, I am moving to other networks.
